Step-by-step explanation:
given: TQ\\RS and PQ\\TS
to prove: ar( PTS)=ar(TQR)
proof: join Q and S to form QS
ar(PTS)=ar(TQS)
same base - TS
same parallels- TS and PQ
(triangles with the same base and between the same parallels have equal area)-(1)
ar(TQS)=ar(TQR)
same base- TQ
same parallels- TQ and RS
(triangles with the same base and between the same parallels have equal area)-(2)
we know from (1) and (2)
ar(PTS)=ar(TQS)
ar(TQS)=ar(TQR)
using Euclids axiom number 1
(things which are equal to the Same things are equal to one another)
ar(PTS)=ar(TRQ)
HENCE PROVED.
PLS MARK ME THE BRAINLIEST.
TKS IN ADVANCE.
